[0022] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] The following is referred to Figs. 1-3 The utility model is explained as follows:

[0024] Embodiment: a shoe with waterproof function, including sole 1 and vamp 2, the front end of vamp 2 is covered with package head 3 (package head 3 is made of plastic or rubber). Package head 3 mainly play the role of reinforcing structural strength, prevent kicking and decoration.

[0025] The above is the prior art, and the present application is improved as follows to solve the problem of water entering the package head vent hole in the prior art:

[0026] The inner side of package head 3 is provided with a heat dissipation groove 4, which is arranged in the front-rear direction, and the heat dissipation groove 4 penetrates the rear side of package head 3. The heat dissipation groove 4 is provided with a plurality of grooves and is arranged in the left-right direction.

[0027] From the structure design, the heat dissipation groove 4 is arranged in the front-rear direction to form a through heat dissipation channel. When rainwater contacts the outer surface of the package head, since the groove opening is directed towards the rear side of the package head, the probability of being directly impacted by rainwater during normal walking is relatively low, and the rainwater flows downward along the outer surface of the package head under the action of gravity, making it difficult to enter the shoe from the groove opening on the rear side. At the same time, the plurality of heat dissipation grooves are arranged in the left-right direction, which not only ensures the structural strength of the inner side of the package head, but also forms a plurality of independent heat dissipation channels, thereby increasing the heat dissipation area.

[0028] In terms of heat dissipation principle, the heat generated in the shoe is conducted to the heat dissipation groove 4 on the inner side of the package head 3 through the vamp 2. Since the heat dissipation groove is through in the front-rear direction, the heat can escape along the groove channel to the rear side of the package head, and then be released to the external environment through the groove opening. This design of heat dissipation channel utilizes the principle of natural air convection, and without additional power device, the effective emission of heat in the shoe can be realized, thereby ensuring the ventilation performance of the shoe.

[0029] The advantage of this technical solution is that by changing the position and direction of the heat dissipation structure, the water problem is solved without affecting the heat dissipation and ventilation. The heat dissipation groove is arranged on the inner side of the package head, which avoids opening the ventilation hole on the outer surface of the package head, thereby fundamentally blocking the way for rainwater to enter the shoe through the ventilation hole. At the same time, the channel formed by the through front and rear heat dissipation grooves not only can discharge the heat in the shoe, but also can make the air in the shoe flow, thereby further improving the ventilation effect. In addition, the combination of the package head made of plastic or rubber material and the structure of the heat dissipation groove facilitates processing and manufacturing, thereby reducing production cost, and having good practicability and economy.

[0030] The rear side of package head 3 is provided with a converging groove 5, which is located at the middle position of package head 3, and the rear end of heat dissipation groove 4 gradually approaches converging groove 5 and is arranged in communication with converging groove 5. The rear end of heat dissipation groove 4 gradually inclines to converging groove 5 and communicates.

[0031] The converging groove 5 is located in the middle area of the rear side of the toe cap 3, which is less affected by the horizontal splashing of rainwater or the front splashing when walking compared to the front end and the left and right sides. The heat dissipation grooves 4 adopt a layout that converges from the rear end to the middle, forming a channel network similar to "fan convergence": each heat dissipation groove 4 extends in the front-rear direction to the rear end and converges to the center of the converging groove 5 at a gradually changing angle, so that the rear end openings of each groove are concentrated in the central area of the rear side of the toe cap. This layout optimizes the geometric position and converges the originally dispersed heat dissipation openings to an area that is less likely to be invaded by rainwater, reducing the probability of rainwater invasion from the spatial position.

[0032] When rainwater contacts the outer surface of the toe cap, it flows downward along the longitudinal direction of the arc surface under the action of gravity, and the middle position of the rear side where the converging groove 5 is located is in the "non-direct impact area" of the water flow path. Since the rear end openings of the heat dissipation grooves 4 are all connected to the converging groove 5, it is equivalent to integrating multiple possible water entry points into a total outlet located in a safe area. Even if a small amount of rainwater contacts the groove opening from the rear side, the rainwater needs to overcome gravity and surface tension to enter the groove in reverse, and the water splashed by the sole during normal walking is also difficult to reach this area, thus forming multiple waterproof barriers.

[0033] Two connection structures of the toe cap 3 and the upper 2:

[0034] Connection structure 1: The edges of the front side, left side, and right side of the toe cap 3 are respectively sealed and fixedly connected with the sole 1, and the other positions of the toe cap 3 are fixedly connected with the upper 2 (using fixed connection methods such as sewing, hot pressing, or bonding). The toe cap and the upper form a rigid whole. The core of this connection method is that the sealed connection of the three edges with the sole blocks the path of rainwater penetrating from the bottom of the toe cap into the shoe, and the fixed connection of the toe cap with the upper ensures the stability of the overall structure.

[0035] Connection structure 2: The edges of the front side, left side, and right side of the toe cap 3 are respectively sealed and fixedly connected with the sole 1, and the other positions of the toe cap 3 are movably connected with the upper 2. This is equivalent to forming a heat dissipation and ventilation space between the toe cap 3 and the upper 2, which helps to improve the heat dissipation and ventilation performance

[0036] The area on the upper 2 corresponding to the toe cap 3 is distributed with a plurality of through holes 6. These through holes and the heat dissipation grooves 4 on the inner side of the toe cap, as well as the movable gap between them, form a through ventilation channel.

[0037] The gap space formed by the movable connection serves as a "heat dissipation buffer zone", and its working principle is as follows: the hot and humid air in the shoe enters the gap through the through hole 6 in the vamp, mixes with the heat discharged from the heat dissipation groove 4 on the inner side of the bag head, and forms natural convection by using the principle of hot air rising. When the foot moves, the relative micro-motion of the bag head and the vamp will squeeze the air in the gap, accelerating the air circulation.

[0038] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
